Procurement Notes

Verify the specific suffix 'FN484C' against official Lattice documentation to confirm package type and temperature grade. Confirm end-of-life status or obsolescence notices prior to procurement planning. Ensure design-in compatibility with required I/O standards and power supply constraints. Cross-reference datasheet revisions to validate pinout and electrical characteristics for final production.

Selection Notes

Select this component when a high-port-count crosspoint switch is required for signals exceeding standard logic speeds. The 256x256 matrix offers extensive connectivity options for complex signal routing tasks. Verify that the 1.8V supply requirement aligns with the system power architecture. Consider the FPBGA-484 package size and thermal dissipation capabilities during PCB layout and mechanical design phases.

Part Context

This part belongs to the LX256 family of crosspoint switches from Lattice Semiconductor. These devices are engineered for applications requiring low-latency signal switching between multiple sources and destinations. The family typically includes variants with different package options and speed grades to suit various density and performance requirements in networking and industrial electronics.

Replacement Considerations

Check Lattice's official discontinuation notices for mature devices. Potential substitutes may include other LX256 series variants with compatible pinouts or higher-performance crosspoint ICs from the same manufacturer. Verify functional equivalence regarding matrix size and supported I/O standards before substitution.
